Abstract
Dynamic pile installation monitoring is an alternate to expensive static compression load testing that when used in conjunction with the second can result in significant cost and time saving for a project while providing additional data across a site. The cost to perform one static load test can be compared to the cost of PDA testing and CAPWAP analyzing five piles. The cost-effectiveness of a load test program where a combination of dynamic and static load tests are performed, as well as the good correlation between static and dynamic capacity interpretations (using CAPWAP analysis) are demonstrated by a case study. The case study describes a load test program that was completed for the process area of the Sempra Cameron LNG project in Louisiana. Subsurface soils consist of Recent and Pleistocene Beaumont Clay soils, typically found in the Texas-Louisiana Gulf Coast area.
